CC497K Bronze vs. Solder Alloy 102

CC497K bronze belongs to the copper alloys classification, while solder alloy 102 belongs to the otherwise unclassified metals. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is CC497K bronze and the bottom bar is solder alloy 102.
